Old Crap

@ March 17, 2014 9:59 PM in Mercury control replacement

I was introduced to ... The R powered a heater in the thermostat which you can change the disks to give you different cycles on the thermostat which was a big thing converting from coal to oil with huge radiators . The heat anticipator replace the disks, now we can just program ..

The RA117 before that was the Mercoide with mercury tubes which lasted forever but was loaded with brass and you can cash in on the mercury too back then and it was slow as Kansas ... Yes if the the motor clapper welded shut on the 117 you would loaded the boiler if you had a low voltage limit . . The ing clapper had to pull in first , the side points on the clapper made the motor clapper ... We use to replace the helix and clappers out in the field and clean the points with files and coat with #2 pencils
The first ones where three wire for the series 10 thermostats ... Those old heat sensor controls where so slow action and easy to throw out of step . Yes that old crap .

look closely

@ March 16, 2014 1:38 PM in Mercury control replacement

I remember that control , the upper makes on temperature rise, it's a B for the circulator the other is the A for winter limit.. They were used in the era of the series 10 summer and winter control that was installed in the side arm , Can't remember the number , top lever hozontal control with a switching relay .....

Dual Aquastat

@ March 14, 2014 1:37 PM in Mercury control replacement

L4081 is an replacement but you will need to change the well . I don't those well adapter kits are still around ... They kinda sucked anyway ... The old control is a helix probe

@ March 14, 2014 12:44 PM in Please help aquastat

Kinda the same in most common systems ... The J can also be used on a 24V and millivolt gas valve and a low limit can also be added ....


@ March 7, 2014 9:21 AM in tenant heat metering

We all know the best option is a separate boiler and oil tank

Another Option

@ March 7, 2014 9:00 AM in What brand of indirect hot water heater would one recommend ?

I like the idea of stainless , but it's a tough metal to weld , that where the issues comes in with leaking stainless tanks ... Turbomax is a nice design with large copper coils where the water runs through ... I do not see too many or heard of any issues with them. What I understand with the correct boiler , circulator and proper size tank , you can size for an endless supply of hot water for your needs .... Which could be good or bad if you have daughters that hog the bathroom :)

Size to the biggest load

@ March 7, 2014 8:42 AM in superstor or amtrol

Size the tank to the biggest load , Either how much water to fill the tub or length of shower . Say tub size is 50 gallon your not going to fill to top ,40 gallon would work..To figure shower its GPM x time ....Say you have 2.5 GPH flow rate shower head and you take a 15 min shower , 2.5gphx15m= 37.5 gallon tank , To figure flow rate take a 5 gallon bucket open shower and time how many gallons in a min ...

Small Efficient Boilers

@ March 6, 2014 5:43 PM in Back up boiler size

When you find out what is needed through your heat loss calculation . You will find out the better smaller oil fire boilers come from Europe ... Like the Buderus G115 ... Well made , three pass, positive pressure boilers and there indirects are well made too ... Throw the outdoor reset on with the remote room sensor ... When the fire cools down the boiler would take over ...

Why not.....

@ March 6, 2014 1:08 PM in Jumper thermostat contacts - ZoneTrol II

....instal a floor sensor thermostat in the radiant bathroom ...

You can also contact Honeywell zoning , I am sure they can help direct you .... Here is your zoning panel ...its really just a matter of directing power between O and B your heat cool switch did it for you before ..... Good luck

Seems like there Spirovent look alike model fails from lack of venting within a year or two ...

Time to call tech support .. the un posted error could be a factory error code not listed

Main vent

@ March 4, 2014 8:06 PM in hissing radiator

Main vent is important to balance a one pipe steam system , you want to charge the mains first , then heat the radiators ... Almost no main vents ?
the panting ... First are your main pipes insulated ?

Heat cycles

@ March 4, 2014 7:44 PM in Baseboard noise

Knock those heat cycles down , gain even comfort , save 20% off your energy bills and kill the expansion noise to get a better sleep . instal an outdoor reset control ..
